In round 1 you are having your first child, which will be a multiple birth. To figure out how many children you'll have go to
www.random.org/dice. Roll 1 dice and what ever number you get is how many children you'll have this round. If you get 1, roll again. Once you have your number, click on that many die to roll.
Odd numbers are boys and even numbers are girls. As far as names, continue to use ones from your catergory, but also chose a theme for your children. It can be as simple as all starting with the same letter.
